Plastic recycling: an underperforming sector ripe for a remake

Plastic recycling: an underperforming sector ripe for a remake

While there is no silver-bullet solution to the toxic tide of plastic surging into our oceans, recycling must form part of the answer. The problem, many experts say, is that current processes are not fit for purpose.

The world produces around 300 million tonnes of plastic waste each year. To date, only 9 percent of the plastic waste ever generated has been recycled, and only 14 percent is collected for recycling now.

The reasons are complex. Not all plastic can be recycled and a lack of public awareness means plastic collections are often contaminated. This can increase the cost of recycling.

In the United States, for example, the introduction of single-stream recycling—where recyclables are not separated in household collections—led to a huge surge in recycling rates, but as plastics became more complex, people started placing the wrong things in their bins. Waste Management, the largest processor of residential recycling in North America, says that one in every four items in recycling bins today is not recyclable.

“Chemicals added to plastic polymers, products made of mixed materials and food packaging contaminated with food waste make recycling difficult and costly,” wrote the authors of UN Environment’s The State of Plastics report.

The need to rethink recycling became more apparent when China, which has imported nearly half the world’s waste since 1992, stopped taking foreign plastic waste this year. China’s decision exposed weaknesses in recycling facilities in many other countries.

There are financial reasons for the shortfalls. Depending on the oil price, it is often cheaper to make virgin plastic while the market for recycled plastic is notoriously volatile, making investors reluctant to commit to the sector.

For years, activists have argued that packaging producers and retailers should pay more to cover the cost of dealing with their waste. While many brands have committed to using more recycled plastic, the pressure is growing for them to do more.

In Britain, the government is said to be planning to charge supermarkets, retailers and major drinks brands tens of millions of pounds more towards the cost of recycling. The strategy would include plans to increase contributions from retailers and producers from an average of about 70 million pounds a year to between 500 million pounds and 1 billion pounds a year. There are also plans to include smaller producers.

The European Commission unveiled a Plastics Strategy in January, saying that its drive to make all plastic packaging recyclable or reusable by 2030 could create 200,000 jobs but only if recycling capacity was multiplied fourfold. The European Union recycles less than 30 percent of its 25 million tonnes of plastic waste each year, and half of that used to be sent to China.

As part of its strategy, the European Union will develop new rules on packaging to improve the recyclability of plastics and increase demand. It wants to see improved and scaled up recycling facilities and a more standardized system for the separate collection and sorting of waste.

The World Bank said in its What a Waste 2.0 report that when waste pickers are properly supported and organized, informal recycling can create employment, improve local industrial competitiveness, reduce poverty and decrease municipal spending.

Citizens also have a role to play but education and information are essential. The World Bank cites the example of Jamaica, where environmental wardens, employed by the National Solid Waste Management Authority, teach their neighbors about environmentally friendly disposal of waste. The communities involved collect plastic bottles and remove plastic litter from shared spaces and drains. They then sell the collected bottles to recyclers.
